A nurse is caring for a client who experienced a lacerated spleen and has been on bedrest for several days. The nurse auscultates decreased breath sounds in the lower lobes of both lungs. The nurse should realize that this finding is most likely an indication of which of the following conditions?

A. Fresh frozen plasma: Fresh frozen plasma contains clotting factors, including factor VIII, but it is not the primary treatment for hemophilia A. While it can be used in emergency situations to temporarily increase clotting factor levels, it is not typically administered prophylactically before dental procedures.
B. Recombinant factor VIII: This is the correct answer. Recombinant factor VIII is the treatment of choice for individuals with hemophilia A. It is administered to replace the deficient factor VIII in the blood, thereby promoting clot formation and preventing excessive bleeding during surgical procedures such as wisdom teeth extractions.
C. Packed red blood cells (RBCs): Packed red blood cells are not typically indicated for the treatment of hemophilia A. While they may be necessary if significant blood loss occurs during the procedure, the primary treatment is replacement of the deficient clotting factor.
D. Prophylactic antibiotics: Prophylactic antibiotics may be prescribed to prevent infection following dental procedures, especially in individuals with bleeding disorders who are at increased risk of infection due to compromised immune function. However, the primary treatment for hemophilia A prior to dental procedures is replacement therapy with clotting factor concentrates like recombinant factor VIII.

A. pH 7.55, HCO3 30 mEq/L, PaCO2 31 mm Hg: These values indicate respiratory alkalosis with metabolic alkalosis. The pH is elevated, indicating alkalosis. The HCO3 level is elevated, indicating metabolic alkalosis, while the PaCO2 is low, indicating respiratory alkalosis. This pattern is not typically seen in chronic kidney disease.
B. pH 7.30, HCO3 26 mEq/L, PaCO2 50 mm Hg: These values indicate metabolic acidosis with respiratory acidosis. The pH is low, indicating acidosis. The HCO3 level is slightly low, indicating metabolic acidosis, while the PaCO2 is elevated, indicating respiratory acidosis. This pattern is not typically seen in chronic kidney disease.
C. pH 7.50, HCO3 20 mEq/L, PaCO2 32 mm Hg: These values indicate metabolic alkalosis with respiratory alkalosis. The pH is elevated, indicating alkalosis. The HCO3 level is elevated, indicating metabolic alkalosis, while the PaCO2 is slightly low, indicating respiratory alkalosis. This pattern is not typically seen in chronic kidney disease.
D. pH 7.25, HCO3 19 mEq/L, PaCO2 30 mm Hg: These values indicate metabolic acidosis. The pH is low, indicating acidosis. The HCO3 level is decreased, indicating metabolic acidosis, while the PaCO2 is within the normal range. In chronic kidney disease, impaired kidney function leads to the retention of metabolic acids, resulting in metabolic acidosis. This pattern is consistent with chronic kidney disease.
